I DOUBLE BEADING AND FORMING MACHINE Filed Oct. 27, 1957 INVENTOR WITNESS I ATTORNEYS Patented July 11, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention. relates to metal working machines, and its general object is to provide what I term a double beading and forming machine, that is primarily designed for heading and forming metal bands or collars for use in connecting blow pipes and the like generally used in factories and mills.

A further object is to provide a machine that is capable of forming a bead on each longitudinal edge of a strip of sheet metal and to roll the same in collar formation in a single operation.

Another object is to provide a machine for use in making bands or collars of the type set forth, from connected strips or pieces of material, which machine will produceco-llars from material of the type mentioned capable of performing their intended function with the same efficiency as collars made from a single strip of sheet material.

A still further object is to provide a machine that is adjustable for use on sheet metal of various thicknesses and in making collars of various diameters.

Another object is to provide a machine of the character set forth that requires no special skill to operate, is simple in construction, inexpensive to manufacture, and extremely efficient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan view of the machine which forms the subject matter of the present invention. I

Figure 2 is a sectional view taken approximately on line 2-2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a sectional view taken approximately on line 3-3 of Figure 1, looking in the direction of the arrows. I

Figure 4 is a sectional view taken approximately on line 4-4 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, the reference numeral I indicates the base of my machine, which is of fiat rectangular formation and has openings adjacent the ends thereof to receive bolts or other similar means for fixing the machine in position for use.

Formed on and rising from the sides of the base I adjacent one end thereof, is the roller frame which includes spaced upright guide members 2 having tongues on the confronting edges thereof to slidably receive bearing blocks for the rollers which will be presently described. Detachably secured to the upper ends of the guide members 2 are strips 3 that bridge the space between the upright guide members to limit the upward movement of the bearing blocks, yet allowing removal thereof, as will be apparent upon inspection of Figure 2.

Journaled in companion bearing blocks arranged in superimposed pairs, and which for distinction are indicated by the reference numerals 4 and 5, are the trunnions 6 and 1 respectively of companion rollers 8 and 9, the roller 8 being disposed below the roller 9 and having a pair of annular grooves l8 therein for cooperation with a pair of annular beads II on the upper roller 9, the beads II being arranged for travel in the grooves, for a purpose which will be later described.

The bearing blocks 4 and 5 are mounted between the intermediate guide members and the ones disposed to the rear thereof, and mounted between the intermediate guide members and the forwardly disposed guide members are bearing blocks I2 which have Journaled therein the trunnions I3 of a forming roller 44 arranged to receive the work from the rollers 8 and. 9, as best shown in Figure 2. The forming roller has annular grooves l5 therein that coincide with the grooves and beads I0 and H, and while all of the bearing blocks are mounted in the guide members, for slidable movement, and for removal therefrom, the bearing blocks 4 and [2 have set'screws 16 secured thereto and rising therefrom, as well as threaded through the strips 3, for adjusting the rollers 9 and I4, so that the roller 9 is adjustable with respect to the roller 8 and the roller l4 with respect to the rollers 8 and 9. The rollers are held in adjusted positions by lock nuts I! threaded on the set screws and engageable with the strips 3.

Two of the trunnions 6 and I extend through their bearing blocks and have keyed or otherwise secured thereto gears I8 that mesh with each other for rotation of the rollers 8 and 9 in unison, and the extending trunnion of the roller 8 is longer than the corresponding trunnion of the roller 9 and has keyed or otherwise secured thereto a drive gear H! which has meshing therewith a pinion 20 that is mounted on one end of a drive shaft 2|, the latter being journaled in upright plates 22 secured to and rising from the base. The opposite end of the drive shaft 2| is shown as having a transverse bore therein for slidably receiving the shank of a crank handle 23 which is held fixed within the bore by a set screw, as shown. However, the drive shaft may have a pulley thereon or other appropriate means, whereby the machine can be driven by suitable power means.

Secured to the upright plates 22 is a work table 24 that preferably has its forward end fixed to the guide members, and the work table has work guides 25 secured thereto and arranged in parallel relation with respect to each other as best shown in Figure 4, which likewise discloses that the work guides include inwardly,

extending flanges 26 disposed in spaced relation with respect to the work table, to receive. the work between the flanges and the table, and to accurately guide the work, which in the present instance are strips A of sheet metal, to the rollers to bead and form the same into connecting collars, as previously set forth and suggested in Figure 2.

In the use of my machine, it will be obvious that a strip of sheet metal is fed to the rollers 8 and 9 for disposal between the same to provide beads on the outer longitudinal edges of the strip, and the beads of the strip are received in the grooves E5 of the forming roller, so that the strip is formed or rolled in collar formation. It will be further obvious that due to the fact, the roller I4 is adjustable, collars of various diameters may be made. It will of course be understood that the collars are completed by riveting or otherwise securing the meeting edges thereof together.

My machine is not only capable of forming collars from a single strip or piece of sheet metal, but scrap metal may be used for that purpose, and in that event small pieces of sheet metal are riveted or otherwise secured together to provide a strip of sufiicient length to a provide a collar and the strip which includes the connected pieces is then run through the machine in the usual manner, as it will be noted that the rollers 8 and 9 are provided with annular grooves 21 and 28 midway their ends to receive the heads of the rivets or spot welding caps, so as to allow free passage of the connected strip through the ma chine, with the result it will be seen that my machine can form the collars from scrap metal which is generally thrown away and the collars so formed are capable of performing their intended function with the same efificiency as collars which are formed from single strips of sheet metal.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be .made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claimis:

A .machine for double beading and forming collars of various diameters from strips of sheet metal and comprising a flat rectangular shaped base, a roller frame including guide members secured to and rising from the side edges of the base, bearing blocks mounted for slidable movement in the guide members, means bridging and detachably secured to the upper ends of the guide members to allow removal of the blocks therefrom, superimposed double beading rollers having annular grooves therein to allow for the passage, between therollers of protruding portions of means connecting pieces of metal together to form a strip, such as the heads of rivets or spot welding caps, a forming roller arranged to receive the beaded strip from the heading rollers and to roll the strip into collar formation, trunnions on each of said rollers jour- 1 naled in the bearing blocks, headed means threaded through the bridging means and secured to the bearing blocks of the upper beading roller and the bearing blocks of the forming 'roller for the adjustment thereof, lock nuts for the threaded means engageable with the bridging means, parallel upright plates rising from the base, means for rotating the beading rollers and including means journaled in the upright plates, a table supported on the upper ends of the upright plates and for receiving the strips, and guide means on the table to facilitate feeding the strips to the beading rollers.
